title: Long-term results of bipolar arthroplasty in osteoarthritis of the hip.
abstract: Bipolar arthroplasty of the hip was introduced by the first author in 1974. From that time until 1988, this type of arthroplasty has been carried out in 1213 hips at the authors' institution. Included is a group of 760 osteoarthritic hips on which follow-up studies have been done at six months, five years, ten years, and 15 years. Studies of the acetabulum show healthy bone preservation as long as 15 years after surgery. A process of floor reinforcement in certain states has also been identified. The relatively simple operative technique has resulted in few postoperative complications. Clinical results as long as 15 years postsurgery compare favorably with two-piece replacement techniques.
